Title:
SYSTEM AND METHOD FOR PITCH CORRECTION
Document Type and Number:
WIPO Patent Application WO/2017/118424
Kind Code:
A1
Abstract:
A system for pitch correction. The interactive surface (1) is embedded with a host, an antenna, a memory unit, a voice input device (3), an audio recognition device, and a media player (2). The function of each light-emitting contact point (4) is determined or changed by the host in accordance with preset programs. Each physical sheet (5) is embedded with an RFID tag (6) and is printed with a set of pitch marks (8) with increasing difficulty levels, and the location of a functioning area on a physical sheet (5) for the light-emitting contact points (4) is determined in accordance with the preset programs, and the light-emitting contact points (4) correspond to the location of the functioning area. Once a physical sheet (5) is placed on the interactive surface (1), the host assigns preset flashing rules to the array of light-emitting contact points (4) in accordance with the preset programs as well as the RFID tag (6) embedded in the physical sheet (5), and generates a preset flashing pattern on the physical sheet (5), and activates touch functions of the corresponding light-emitting contact points (4). The visible feedback provides users a straightforward understanding how much their voices deviate from the reference pitches.
